%0 Journal Article %A Cobos, Fernando %A Fernández-Martínez, Pedro %T Reiteration and a Wolff Theorem for Interpolation Methods Defined by Means of Polygons %D 1992 %@ 0039-3223 %U https://hdl.handle.net/20.500.14352/57280 %X We prove a reiteration theorem for interpolation methods defined by means of polygons, and a Wolff theorem for the case when the polygon has 3 or 4 vertices. In particular, we establish a Wolff theorem for Fernandez' spaces, which settles a problem left over in [5]. %~
